Answer 1

To rotate the point \( (9, 5) \) 270 degrees clockwise, we can use the rotation formula. In general, a counterclockwise rotation of 270 degrees is equivalent to a clockwise rotation of 90 degrees.

The formula for rotating a point \( (x, y) \) counterclockwise by 90 degrees is:
\[
(x, y) \to (-y, x)
\]

Thus, rotating \( (9, 5) \) 90 degrees clockwise gives:
\[
(9, 5) \to (-5, 9)
\]

Therefore, the new point after a 270-degree clockwise rotation is \( (-5, 9) \).

The correct response is:
\[
(-5, 9)
\]
